that the valley memory value is being displayed.
•
HiLo
- toggle between
Hi
and
Lo
displays. This function allows the remote input to be used
to toggle between peak and valley memory displays. The first operation of the P button will
cause the peak memory value to be displayed, the next operation will give a valley memory
display.
PHi
or
PLo
will flash before each display to give an indication of display type.

OFF, EASY, NONE
or
ALL
Default Value:
OFF
Access mode - the access mode function
ACCS
has four possible settings namely
OFF, EASY,
NONE
and
ALL
. If set to
OFF
the mode function has no effect on alarm relay operation. If set
to
EASY
the “easy alarm access” mode will be activated. Refer to “Easy alarm relay adjustment
access facility” section. If set to
NONE
there will be no access to any functions via
FUNC
mode,
entry via

Number of input bits
Display:
INPt bitS
Range:
1
to
20
or
1
to
31
Default Value:
14
Input bits - allows selection of the number of input bits from 1 to 20 for parallel inputs or 1 to 31
for strobed or addressed inputs.
5.23
Sign bit on or off
Display:
SIGN
Range:
on
or
OFF
Default Value:
OFF
Sign bit
on
or
OFF
(parallel binary input only) - Example: if set to on then, with 16 bit binary
selected, the most significant digit will be used as the sign bit with 0 on the most significant digit
being positive and 1 on the most significant digit being negative. e.g. 0111 1111 1111 1001 will
show as
32761
on the display and 1111 1111 1111 1001 will show as
-7
(-7 being the twos
compliment of 111 1111 1111 1001). Thus the display with 15 bits plus a sign bit can display any
number from
-32768
to
32767
. If set to
OFF
none of the data bits will be treated as a sign
bit and all values will be positive.
